Original Game
Navia Dratp is a collectible miniatures strategy board game created by Bandai, designed by Koichi Yamazaki. Originally released in 2004.
Board & Piece Art
The board graphics and non-compact piece images are from the Virtual Navia Dratp (VND) module for the VASSAL game engine. The VND module was created by Pascal Ludowissy (March 2006) and is available from the VASSAL module library.
“The creation of this 'virtual' adaptation, which was sometimes quite a challenge for a non-coder like me, shows just how strong the appeal of this great game is.”
Pascal kindly gave his blessing to use these assets in this project. Thank you, Pascal!
Pascal's permission covers his own adaptation work. The game components his images depict and were photographed from — the pieces, cards, and board — remain the copyright of Bandai.
Bandai never produced a card for Persephone — the card shown on this site is a custom creation by Dudical. Thank you, Dudical!
This Implementation
A web-based implementation built with Elixir, Phoenix LiveView, and a lot of help from Claude (Anthropic). This is an unofficial fan project — not affiliated with or endorsed by Bandai.
Claude kept a running development journal as the project was built — the bugs, the dead ends, the rules arguments, and one hotseat game it lost.
